i noticed in my car lately that the a/c is not cold as it should be. i have recharged it with refrigerator coolant and still nothing. any ideas on that?

another problem is even when im putting the dial at 4 on my air, there seems to not be that much air blowing out of the vents? any ideas on how to fix that also?

thanks

 

it may be your ac compressor going bad.

 

Add refrigerant without measuring the pressures? You may have overcharged it.

 

check your low pressure side hose and see if it has any cracks in it
